Engineers at the Korea Research Institute of Standards and Science (KRISS) have developed a new ultrasonic sensing technology that can detect structural defects in dangerous environments where ...
But, similar bursts from other sensors in close proximity may interfere with the echo timing. When that happens, the sensors suffer from a condition called cross talk. Interference from cross talk ...
Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
